Mastering HART: HART Protocol explained for Beginners

[@CarlosGutierrez-cb6jw]

In some sections of the video, there are two overlapping voices that don't allow for a clear understanding or the ability to stay focused because one ends up trying to understand what both voices are saying.

[@spinstitute2440]

Very well explained. Thanks for your efforts

[@TheCraigrenard]

Please do this video again as the audio overlaps and can not be heard clearly

[@InstrumentCalibration]

Hello Craigrenard Sorry for the inconvenience. I will do it again. Thanks for letting us know.

Hello Siva Thank you for watching our video.

[@mustafanazari2862]

Thank you for information

[@InstrumentCalibration]

Thanks for your valuable feedback. Kindly subscribe to the channel for upcoming videos !!

[@alexanderdmello2749]

I think there is unintentional audio and audio overlap through the Intro and What is HART Technology. I appreciate your service.

[@InstrumentCalibration]

Hello Alexander Thank you for your valuable feedback. We really appreciate it. And we definitely try to improve the quality of our video. Once again thank you.

[@prakashkaran-ij5sf]

Yes, can you reupload this video, the audio is overlapping. Can't understand the concept.

hart protocol is hybrid digital and analoge, the digital consist from 4 values 1-primary 2-secondary 3-ternary 4 quarter, hart based on Bell202 with modulation of FSk. Hart transmitter working with 3 type of command, 1- common practice 2- universal 3- specific Each one have different task to do Hart working with method of master and slave Each loop can contain in maximum 2 master in one loop. my regards from IRAQ

In your presentation you showed 250 ohm resistor connect with +ve side and also -ve side of power supply. Which one we follow

[@InstrumentCalibration]

Hello Abdulla It will work on both way. However, normally, It should be connected on +VE (positive) side of power supply.

[@ritushilpi1]

I didn't understand why 250 ohm resistor is used ? Is it really to bypass the capacitors

[@ibrahimnasr2436]

Is there a simulation program for calibration training and instrumentation connections?

[@medmiro6948]

The same question if you find it tag me please Big respect

[@InstrumentCalibration]

Hello Ibrahim I I will make one video on this, if I have content in future related this simulation.

@@medmiro6948 Hello MEd I will make one video on this topic, If i have content in future.

[@ARUNKUMAR-bf7od]

Dcs and plc operation video we want

[@InstrumentCalibration]

Hello Arunkumar I will make one video on this topic in future

[@ravivarmma]

@callibration academy, could you please redo the video. The audio is overlapping with some other video

[@InstrumentCalibration]

We are working on that.Thanks for the feedback

[@DouglasHenrique-ur8lv]

Hello, I have been finding different ways to connect the hart communicator to the instrument. 1_Resistor in series with '+' 2_Resistor in series with '-' And in these two cases, the hart communicator pointers are connected to the instrument's '+' and '-' terminals. 3_The resistor in series with '-' of the loop and the hart communicator with the leads at the ends of the resistor. As seen in the manual. Is there any difference, does it change according to the application or instrument? Could you help me with this question?

[@InstrumentCalibration]

Hello Douglas Thanks for your comment. Technically, 250 ohm resistor need to be connect in series with + terminal. However, it does not make any difference if you connect with negative terminal. You can still connect HART communicator to device. Is there any difference, does it change according to the application or instrument? No, it does not have any relationship with application.
